' and theI hub ol the aid disk G screws on thr bearing lll, so as to allow of taking up any wear of tho'rolor B within. thvv casing A, by

the. operator scrrwing the disk G inwardly on the bilaring li). The hub of the disk G is engaged hy a nut G2 screwing on the bearing E to lock the dish in placa after the desired j adiusniient is inado. The head G is providid with an exhaust hast G3 connected by si-gniontal ports b with the interior ofthe. casing` A, at the has@ ond thrrof, the admission por rs (I, und tho oxhaust ports b being oppol sito the space botwocn th(l rotor B andthe inner surlaro ol the casing' A.

l, The intrrior surface of the Leasing A is prol ridad with `sunlzon pockets or buckets A",

l and similar poclwts or buckets B are sunken l in thil peripheral face ol' the rotor E'. The

l pockets A and B are arranged in transverse l rniristoring rows, and tho pockets A of the casing A @xtond in a spiral direction on the i inner surfaoroi' the casing' A, and the pockets i extend in a likel spiral direction on the exterl nalsuriaosofthcrotorB. The. pockets A and l i are approxiniatrly triangular in v shape,

s. and tho roar vdg'os A? of tho pockets A are doop whih` thix forward ends Aware shallow l and merge with the interior surface of the l casing A. Tho pockets B have their forward ends B2 doop, while their rear ends B3 lare l shallow and morge with they peripheral face l oi the rotor l. By reference to Fig. 7 it Will l also be noticed that the forward shallow ends l A3 of the'noolwts il overlap the rear shallow l ends B oi tho pockets B, so that the steam l or other motivo agentn ono transverse row l i i l l i i l l i i ol pockets A. can pass into the pockets B of tho rif-)1t following row of pockets in the rotor l, so that the motive agent can. gradib ally pass through they turbine l'roin th( apex vnd oi' thil turbine to the busi) 0nd thoreof. 'ly making tho rotor B and thv casing A ooniunl in rho nnmnor dosorilzcd, thil pockets l5 and il. (van hv rviidily inoroasnd in size l'roni the apex ond ol' thv turbine to the base 0nd llurioi', lo allow of usingr the motivo agr-ont Nipansivoly.

ivvhi'n the *urbino is running; tha motive ngint pnssos from thv admission Ghost F by l way ol the ports 1.', into tho casing' A, between tho inni-r surliaci f lwrool" and the, external sur'aoo ol the rotor B, so that the motive` the next or second row of rotor pockets B', by the overlapping ot' the latter pockets with the first row ot' pockets ot the casing A. In a like manner the steam passes from the second row ot pockets A in the casing A to the third row oi' pockets B in the rotor B, and so on throughout the length of the turbine, until the exhaust motive agent linally passes by Way o1" the ports l) into the exhaust chest G3, lromwhich the exhaust motive agent is carried oit by' an exhaust pipe l to a suitable place of discharge.

The admission ports t and the exhaust ports t) are arranged relative one to the other in such a maniier that when one set of ports is open the other is closed, and vice versa. Thus when the ports a are opened the steam passes in to the casing A at4 the time the ports t are closed., so that the steam is confined in the turbine for the time l'ieing, and owing to the increase in the size of the pockets, as above described, tht` steam is used expansively. vlt will also be noticed that by the arrangement described a pulsating action of the motive agent in its passage through the turbine `is had, that the motive agent acts pulsatingly on the rotor during its passage through the turbine,

B v constructing a turbine in the manner described, the motive agent is utilized to the vfuliest advzmtage, as the motive agent aets by impact and pressure and is capable ol' expanding during its passage through the turbine.

The turbine is ver)Y simple and durable in construction, and composed of comparatively fev.' parts, not liable easily to get outI ot' order.
